Reaction Steps
Step P (1): To a solution of 4-bromo-3-methoxyaniline (0.500 g, 2.48 mmol) in dichloromethane (10 mL) was added 1,1′-thiocarbonyldipyridin-2(1H)-one (0.575 g, 2.48 mmol). The resulting mixture was stirred at rt for 3 h. The crude reaction mixture was loaded onto silica gel and purified using silica gel chromatography (3-60% EtOAc/hexanes, linear gradient) to afford 1-bromo-4-isothiocyanato-2-methoxybenzene (0.48 g, 75% yield) as an off white solid. LC-MS (M+H)+ 244.0. 1H NMR (400 MHz, methanol-d4) δ ppm 7.53 (d, J=8.56 Hz, 1 H) 6.94 (d, J=2.27 Hz, 1 H) 6.79 (dd, J=8.56, 2.27 Hz, 1 H) 3.86 (s, 3 H).
